F5: Devastation, Survival, and the Most Violent Tornado Outbreak of the 20th Century tells a story from the world's most violent tornado outbreak on record--the April 4, 1974 Super Outbreak. The Super Outbreak featured the most tornadoes ever recorded in a single day, 148, and also had an unprecedented number of violent F4 and F5 tornadoes--six F5 tornadoes and 24 F4 tornadoes (for comparison, the past five years have had one F5 tornado and 15 F4 tornadoes.)| Permalink | A A A |
